It measures the resistance of the earth connection directly on the connected earth conductor, without disconnecting the conductor.\u003c\/p\u003e\n\u003cp\u003eTypical applications include grounding checks on transmission towers, storage tanks, and industrial plants, as well as on lightning protection systems and PV installations with multiple earth paths. The clamp also supports leakage current and AC current measurement up to 60 A, accommodates conductor diameters up to 32 mm, and complies with CAT IV 600 V.\u003c\/p\u003e\n\u003ch3\u003eGround Resistance Measurement in Multiple-Earthed Systems\u003c\/h3\u003e\n\u003cp\u003eThe measurement principle uses two separate coils in the clamp head. One coil inductively couples a test voltage into the earth conductor inside the jaw, while the second coil detects the resulting current. For this method to work, multiple parallel earth paths must be present so that a test current can flow. At least two parallel earth paths are required.\u003c\/p\u003e\n\u003cp\u003eFor resistance measurement, the instrument provides 10 ranges from 0.20 Ω to 1600 Ω. The lowest specified measurement value with stated accuracy is 20 mΩ. Range selection is automatic, and the measured value can be frozen on the display with the HOLD key. For work in dimly lit environments, the display is equipped with a switchable backlight.\u003c\/p\u003e\n\u003ch3\u003eLeakage Current, Load Current, and Additional Functions\u003c\/h3\u003e\n\u003cp\u003eIn addition to measuring the resistance of the earth connection, the FT6380-50 also supports AC current measurement. With its lowest current range of 20 mA, the clamp can detect small leakage currents, while load currents up to 60 A can also be measured. Current is measured using a True RMS method.\u003c\/p\u003e\n\u003cp\u003eA selectable filter function acts as a low-pass filter during current measurement and suppresses higher-frequency components, such as those caused by switching power supplies or inverters. During resistance measurement, the filter function stabilizes the display by averaging the measured values.\u003c\/p\u003e\n\u003cp\u003eA configurable threshold alarm is also available and can be set separately for resistance measurement and current measurement. The internal memory can store up to 2000 readings from both functions.\u003c\/p\u003e\n\u003ch3\u003eOptional Bluetooth Communication\u003c\/h3\u003e\n\u003cp\u003eWith the optional Z3210 Adapter, the FT6380-50 can be expanded with Bluetooth communication. Readings can be transferred to a smartphone or tablet and documented in the GENNECT Cross app. The app supports linking readings with photos, maps, and additional information from the measurement site.\u003c\/p\u003e\n\u003cp\u003eIn HID mode, the clamp sends readings as keyboard input directly to the selected application, for example to Excel or input fields in custom software solutions.\u003c\/p\u003e\n\u003cp\u003eThe FT6380-50, powered by two LR6 batteries, provides a typical operating time of about 40 hours without the Z3210, or about 35 hours with the Bluetooth Adapter installed and wireless communication enabled. It is ready for use immediately after power-on, with no zero adjustment required.\u003c\/p\u003e\n\u003cp\u003eThe supplied reference loop allows a quick functional check before measurement. Like all HIOKI current measuring instruments, the FT6380-50 was developed in Japan and is manufactured at HIOKI’s own production facilities in Japan.\u003c\/p\u003e\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cp\u003e• FT6380-50 Earth Ground Clamp\u003cbr\u003e• Carrying Case\u003cbr\u003e• Resistance Check Loop\u003cbr\u003e• Strap\u003cbr\u003e• Instruction Manual\u003cbr\u003e• Operating Precautions\u003cbr\u003e• 2 × LR6 AA Alkaline Batteries\u003c\/p\u003e\n\u003ch3\u003eRelated Products\u003c\/h3\u003e\n\u003cp\u003e• FT6380-90 Earth Ground Clamp\u003cbr\u003e• Z3210 Bluetooth Adapter\u003cbr\u003e• FT6031-50 Earth Resistance Tester\u003cbr\u003e• FT6031-90 Earth Resistance Tester\u003cbr\u003e• FT6041 Earth Resistance Tester\u003cbr\u003e• FT6041-91 Earth Resistance Tester Kit\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Hioki","offers":[{"title":"Default Title","offer_id":58412285133132,"sku":"70048807","price":1088.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/2245\/6652\/files\/FT6380-50_1_web.jpg?v=1786729443","url":"https:\/\/www.testequity.co.uk\/products\/hioki-ft6380-50-70048807","provider":"TestEquity UK","version":"1.0","type":"link"}
